摘要:
A process of copper plating a through-hole in a printed circuit board, and the printed circuit board made from such process. The process comprises: providing a printed circuit board with at least two copper interconnect lines separated by an insulator in the vertical direction; providing a through-hole in the printed circuit board in the vertical direction such that the interconnect lines provide a copper land in the through-hole; applying a seed layer to an interior surface of the through-hole; removing an outermost portion of the seed layer from the interior surface of the through-hole with a laser; applying copper on the seed layer.
